Problem:

When connecting to Mainframe Access 3.0 on the mainframe, from Mainframe Express Enterprise Edition on the PC, the connection is not found.  MFA does not show any errors in the MFA log.

Is there an easy way to detect this..?

Resolution:

Using the F MFA, DISPLAY TCPSTATUS and F MFA,DISPLAY LU commands as shown below...

Shows problems in connecting to MFA via TCP.

This is due to an error in the MFA VTAM definition that is using DLOGMOD information (IBMRDB or #INTER), as it was not created in VTAM correctly.

Correct this error in VTAM and retry Mainframe Access.
